CAS No 107-21-1 Industrial Grade 99% Mono Ethylene Glycol

Tlhaloso e Khutšoanyane:

Ethylene glycol (lebitso la IUPAC: ethane-1,2-diol) ke motsoako oa lintho tse phelang (a vicinal diol) ka foromo (CH2OH)2. Haholo-holo e sebelisetsoa merero e 'meli, e le lisebelisoa tse tala ha ho etsoa likhoele tsa polyester le li-antifreeze formulations. Ke seedi se se senang monkgo, se se senang mmala, se se ka tukang, se se bonalang. Ethylene glycol e na le tatso e monate, empa e na le chefo libakeng tse phahameng.
